I have a wall that's 2" deep. I'm using 4" square boxes for the outlets, as normal x-gang boxes are too deep. I'm need a 4-gang switch bank in one place. Would it be acceptable/wise to cut the ends off of 2 4" boxes, then glue them together (likely with a couple extra scraps on the top/bottom to strengthen it? Alternatively, could I cut a 4 gang box to the right depth and glue on some cover plats to form the back of it?
And if that's absolutely not an option for some reason, anyone have a source for 4-gang boxes that are 2" deep? I've found 1-gang boxes at Allied Moulded, but their larger boxes are still too deep.
